CK5228E Double Column CNC Vertical Lathes

The CK5228E Double Column CNC Vertical Lathe is engineered for machining components up to 2.8 metres in diameter, making it suitable for larger rotors and flanges than the CK5225E. Its frame is constructed from HT300 cast iron, heat-treated for thermal stability, and features a double-column structure to minimise deflection under heavy loads. The platform uses a four-step mechanical drive with DC motor stepless speed control, allowing constant linear velocity cutting across varying diameters. Precision components include P3-grade ball screws and German INA bearings on lead screws, aligned to JB/T9934.1-1999 standards.

The beam guide system employs supersonic induction-hardened surfaces with a rolling-sliding compound design, reducing friction while maintaining rigidity. The vertical tool holder uses QT600-3 ductile iron ram for high-torque cutting, with sliding surfaces coated in plastic for durability. Automatic lubrication is applied to all guides via timed pumps. Optional configurations include static pressure bearings (10 ton capacity) or constant current oil systems (16-20 ton), and closed-loop feedback for enhanced positioning accuracy. Gear trains are Grade 6, ensuring low noise and smooth operation.

This model is primarily selected by foundries, shipbuilding, and power generation equipment manufacturers for large-scale component production. Buyers often require it for continuous batch runs where dimensional consistency is critical. The machine is shipped in export crating with lifting lugs and requires professional setup. Installation includes alignment, calibration, and safety system checks. Documentation is provided in Chinese; English manuals are available upon request. No warranty terms are stated in the listing.

Dalian Yimei Machinery Co., Ltd. is based in Zhuanghe, Dalian, Liaoning Province, China, and operates as a manufacturer of vertical CNC lathes. The company is listed with a harbor trust tier, indicating it has passed basic supplier verification through document submission. There is no public data on company size, years in operation, or export volume. The supplier does not claim certifications such as ISO 9001 or CE, nor does it list client names or production capacity.

The company’s product development is described as independent, with emphasis on modular design and manual operation compatibility. No evidence of R&D facilities, testing labs, or after-sales service centers is provided in the listing. The response rate is recorded as 0.00%, and average response time is not available, indicating limited communication capacity. Buyers should treat this as a direct manufacturer without third-party service guarantees.
